2010-02-12s3:dbwrap_ctdb: fix db_ctdb_fetch_db_seqnum_from_db() when NT_STATUS_NOT_FOUND.Michael Adam1-1/+5
Don't treat this as an error but return seqnum 0 instead. Michael
2010-02-12s3:dbwrap_ctdb: maintain a database sequence number that bumps in transactionsMichael Adam1-5/+116
For persistent databases, 64bit integer is kept in a special record __db_sequence_number__. This record is incremented with each completed transaction. The retry mechanism for failing TRANS3_COMMIT controls inside the db_ctdb_transaction_commit() function now relies one a modified behaviour of ctdbd's treatment of persistent databases in recoveries. Recently, a special treatment for persistent databases had been introduced in ctdb (1.0.108) to work around the problems with the orinal design of persistent transactions. Now with the rewrite we need to revert to the old behaviour that ctdb always takes the newest copies of all records. This change also paves the way for a next step, which will make recovery use the db seqnum to tell which node has the newest copy of a persistent db and use that node's copy. This will greatly reduce the amount of data transferred with each recovery. Michael
2010-02-12s3:dbwrap_ctdb: change db_ctdb_transaction_store() to return NTSTATUS.Michael Adam1-18/+12
The return values calculated by the callers were wrong anyways since the new marshalling code does not set the local tdbs tdb error code. Michael

2010-02-12s3:dbwrap_ctdb: start rewrite of transactions using the global lock (g_lock)Michael Adam1-320/+160
This simplifies the transaction code a lot: * transaction_start essentially consists of acquiring a global lock. * No write operations at all are performed on the local database until the transaction is committed: Every store operation is just going into the marshall buffer. * The commit operation calls a new simplified TRANS3_COMMIT control in ctdb which rolls out thae changes to all nodes including the node that is performing the transaction.

2010-02-12s3: Implement global locks in a g_lock tdbVolker Lendecke2-5/+662
This is the basis to implement global locks in ctdb without depending on a shared file system. The initial goal is to make ctdb persistent transactions deterministic without too many timeouts.
2010-02-10util: rewrite dlinklist.h so that DLIST_ADD_END() is O(1)Andrew Tridgell1-59/+111
This changes the meaning of the ->prev pointer in our doubly linked lists to point at the end of the list from the front of the list. That allows us to implement DLIST_ADD_END() and related functions in O(1) time, which can be a huge saving in many places in Samba. This also means that the 'type' argument to various DLIST_*() macros is no longer needed, but I have left it in for now to keep the patchset small, which will make it easier to revert if any problems are found. In the future we should remove the 'type' arguments. (jra. Move the one use of DLIST_TAIL over to the new macros).

2010-02-10Temporary changes to dlinklist to keep the implementation static whilstJeremy Allison1-0/+16
uses of (list)->prev are moved over to DLIST_PREV. This will be replaced when the final (new) version of the dlinklist.h header is added. Jeremy.
2010-02-05s3-events: make the old timed events compatible with teventAndrew Tridgell1-2/+19
tevent ensures that a timed event is only called once. The old events code relied on the called handler removing the event itself. If the handler removed the event after calling a function which invoked the event loop then the timed event could loop forever. This change makes the two timed event systems more compatible, by allowing the handler to free the te if it wants to, but ensuring it is off the linked list of events before the handler is called, and ensuring it is freed even if the handler doesn't free it.

2009-12-05s3:dbwrap_ctdb: increase the number of commit retries 5-->100Michael Adam1-1/+1
This is to cope with timeouts when recoveries and transactions collide. Maybe 100 is too hight, but 10 or even 20 have been too low in a very busy environment. Michael

2009-12-04s3: check if glibc has broken posix_fallocateBjörn Jacke1-1/+1
2009-12-02Restructure the ACL code some more, get the internal semanticsJeremy Allison1-0/+20
right. The previous bugs were due to the fact that get_nt_acl_internal() could return an NTSTATUS error if there was no stored ACL blob, but otherwise would return the underlying ACL from the filysystem. Fix this so it always returns a valid acl if it can, and if it does not its an error to be reported back to the client. This then changes the inherit acl code. Previously we were trying to match Windows by setting a minimal ACL on a new file that didn't inherit anything from a parent directory. This is silly - the returned ACL wouldn't match the underlying UNIX permissions. The current code will correctly inherit from a parent if a parent has any inheritable ACE entries that apply to the new object, but will return a mapping from the underlying UNIX permissions if the parent has no inheritable entries. This makes much more sense for new files/directories. Jeremy.
2009-12-02s3: prefer posix_fallocate for doing "strict allocate"Björn Jacke1-0/+14
posix_fallocate is more efficient than manual zero'ing the file. When preallocation in kernel space is supported it's extremely fast. Support for preallocation at fs layer via posix_fallocate and fallocate at kernel site can be found in Linux kernel 2.6.23/glibc 2.10 with ext4, XFS and OCFS2. Other systems that I know of which support fast preallocation in kernel space are AIX 6.1 with JFS2 and recent Solaris versions with ZFS maybe UFS2, too. People who have a system with preallocation in kernel space might want to set "strict allocate = yes". This reduces file fragentation and it's also safer for setups with quota being turned on. As of today most systems still don't have preallocation in kernel space, and that's why "strict allocate = no" will stay the default for now.
